    Description: Here we present a multi-proxy record from palaeolake Fucino (Abruzzo, Central Italy), acquired during the F1-F3 drilling campaign. This is the first continuous and high-resolution palaeoenvironmental record in the central Mediterranean region continuously spanning over the last two glacial-interglacial cycles and providing an independent chronology. The record consists of a core composite resulting from two parallel and adjacent core series (F1 and F3). Cores were analysed via high resolution XRF scanning and through geochemical, mineralogical and grain-size analyses on discrete samples. Selected XRF elemental counts (Ca, Ti and Zr), Total Nitrogen (TN), Total Organic and Inorganic Carbon (TOC, TIC), X-ray powder diffraction and grain-size data are used to develop proxies for local environmental processes strictly dependent on the hydro-climatic regime of the Central Mediterranean region. The chronology of the record is based on 17 radioisotopically dated tephra layers interbedded within the sedimentary succession. 14C and 40Ar/39Ar age points are interpolated with the bayesian age modelling package Bacon allowing a robust assessment of age uncertainties.

    Description: Few palaeoclimate archives beyond the polar regions preserve continuous and datable palaeotemperature proxy time series over multiple glacial-interglacial cycles. This hampers efforts to develop a more coherent picture of global patterns of past temperatures. Here we show that Mg concentrations in a subaqueous speleothem from an Italian cave track regional sea-surface temperatures over the last 350,000 years. The Mg shows higher values during warm climate intervals and converse patterns during cold climate stages. In contrast to previous studies, this implicates temperature, not rainfall, as the principal driver of Mg variability. The depositional setting of the speleothem gives rise to Mg partition coefficients that are more temperature dependent than other calcites, enabling the effect of temperature change on Mg partitioning to greatly exceed the effects of changes in source-water Mg/Ca. Subaqueous speleothems from similar deep-cave environments should be capable of providing palaeotemperature information over multiple glacial-interglacial cycles.

    Description: Study of the climate in the Mediterranean basin during different historical periods has taken on a particular importance, particularly regarding its role (together with other factors) in the evolution of human settlement patterns. Although the Roman age is traditionally considered a period with a favourable climate, recent studies have revealed considerable complexity in terms of regional climate variations. In this paper, we compare the hydrological change from speleothem proxy records with flood reconstructions from archaeological sites for Northern Tuscany (central Italy). We identify a period of oscillating climatic conditions culminating in a multidecadal dry event during the 1st century BC, followed by a century of increased precipitation at the beginning of the Roman Empire and subsequently a return to drier conditions in the 2nd century AD. The period of rainfall increase documented by the speleothems agrees with both the archaeological flood record as well as historical flood data available for the Tiber River, ca. 300 km to the south. These data also suggest a return to wetter conditions following the 3nd and 4rd centuries AD.
